Specification o Letters Patent.

Patented May 3U, 1922.

lo it known that l, lineaire A. Kohn, a eilizen ot" the United States. residing at Cincinnati. in the (-ountiv ot Hamilton and State fhio have invented certain new and use-- tui llinproveinents in Electric Switches, ot `which the following; is a specification.

lily invention relates to electric switches, chilly such as are applicable tor use in #or iection with. electric spot-lights for ve-v ha'es, such as automobiles, .motor boats, and o... n* vehiclesv vide a switch which is readily operable in a relation such as that stated; further. to provide a switch which is readily assembled in novel manner; fur-then to provide novel means for applying a switch to the body of an electric spotlight; further to provide 'novel means which readily adapt themselves in novel manner to the curvature oli the body of a spot-light; and, further, to provide novel means whereby quick and effec tive electric Contact is made in the switch, and whereby the contact maybe made and broken with snap movements.

The invention will be further readily understood from the following description and claires, and from the drawing. in which latiiig. 1 representsa perspective view of a spotlight shovviirg; my invention applied thereto.

ligj. 2 is an axial section of my improved u device, 'aken on the line 2-2 of Fig.v l, showing the switch in open relation.

Fig. 3 is a similar View; oi the same, showirm the switch in closed relation.

liig. 4f is an inside end elevation ot' my improved device.

Fig. 5 is an outside end elevation of the same.

Fig. 6 is an axial section of the contactend of the axially movable stem.

Fig. 7 is a cross-section, taken in the planev lt is the object of my invention to pro- .material This base comprises `the layers 27,

lens 16, is provided to close the front of the lamp.

Electric means are ]n'm'icled 'for the electric light bulb, shown as electric conductors 1i), 20, connecting in suitable manner. with the terminals ot the bulb, and having); Woven insulation thereabout, the electric conductors with their insulation continuing through a hole 21 in the casingr ot the lani'p as a flexible cable (lne ot the conductors is interrupted for the reception ot a switch 25, which is secured to the Wall ofthe body.

The switch comprises a base of insulating 28, 29. Holes are in the/layers. These holes register with each other. A sleeve 33 is received through the holes, the sleeve hav-v ing an annular shoulder 3l at one end thereof. The sleeve is :lso received through a hole 35 in the casino. The sleeve is threaded at its outer end` a nut 36 being received thereover and clampingV the base-members and the Wall ot' the casing together.

An axially slidable stein 38 is received through the sleeve. This stem has a limiting part thereon`v shown as au annular flange 39, which acts as a stop to limit the inward movement of the stem. The stom is also provided with u handle or knob Ail), by nii-ans ot which the stein may be pulled outwardly` and the stein may be pushed inwardly by endvsise pressure thereon. The stein is provided with an inner reduced end ill. 'forming au annular shoulder 42. An insulatiim` washer i3. exemplified as a fiber disk. is received over this reduced end against the shoulder. .in insulating washer 44. exemplified as a liber disk. is provided with au elei:ti'oeoniliictive periphery 45, eX- l emplitied for instance. asa .ring` ot copper which is provided with flanges 46, 47, at the respective sides ot' the disk Jfor securing the same to the disk. and forms a conductive ring' having; au insulatingr body. This latter Washer is received over the reduced end ot the stem upon the Washer 43, and the reduced end ol: the stem is upset or flattened tor irn'ily securing the Washers to `the stem. The outwa rd nio'. ement of the axially movable stein is limited by the insulating Washer 42%, which inipinges the inner end of the sleeve l lnlloetro-condurtivo lingers 5l. made preferably ot spring' clcetro-conductivematerial, are secured to the base. Each comprises a Mimes y y conductive clips, each of said clips having aange .at the other side of said last-named layer, the'respective flanges of, said springngers and the respective flanges of said clips being at opposite ends of said 1ayer,'

said layers between said spring-fingers, said ,sleeve provided with a ange atene side 'of said1ayers,gmeans atrthe other side of said :layerslconnecting AWith said' sleeve for @im me demping said iayers together, an axialiy movable stem in said sleeve, and an electrocondnetive peet and en insulating part on said stem arranged to respectively coaet with said spring-fingers by opposite axial movements of said stem.

In testiifzeonyv whereof, have heeunto signed my name in the presence of two sui seibing Witnesses. I
